i agree with ahussains here, no point digging up the past. many facts are shrouded in controversy since both sides exaggerated and lied about losses.
but if you really want the figures here is data from neutral sources. i believ thats about as accurate as it gets.
1948 War: about 1500 dead on each side
India Pakistan War 1947-1949
1965 war: India 3000, Pakistan 3800
India Pakistan War 1965
1971 war: India 2500, Pakistan 9000
Indo-Pakistan Wars - MSN Encarta
the 1971 casuality figures are subject to doubt. wikipedia states india lost over 3000 and pakistani casuality figures are missing.
about the loss of aircraft, naval vessels and armoured vehicles, i have to say i dont know. someone had posted a neutral source about aircraft losses, but i cant find it now
